Need help with graphing?. well its very easy to start from.
The answer 3.8 to the nearest hundreds is 3,800
Answer:
D
Step-by-step explanation:
Since there are two types of values here: tokens and dollars, we will need to use the same value across numerators and denominators in the ratio.
Choice D has 11 tokens over $2 equals to t tokens over $16. In both fractions the numerator is tokens and denominator is dollars.
Surface area of cylinder = 2πrh + 2πr^2
SA for cylinder A = 2π x 2 x 2 + 2π x (2)^2 = 8π + 8π = 16π
SA for cylinder B = 2π x 2 x 4 + 2π x (2)^2 = 16π + 8π = 24π
You don't multiply liters of gasoline by distance.
They are<u> directly proportional </u>- the more gasoline you have the longer is the dictance you can go.
So it's <u>cross multiply</u>.
Another examlpe:
you are paid by hour for your work. The more hours you have worked, the more you are paid:
hours payment
2 h $36
5 h x
![x=\dfrac{5\cdot36}2=90](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B5%5Ccdot36%7D2%3D90)
You would multiply 10•70 if they were inversely poportional values
For example:
1. speed and time of ride by given distance {the greater the speed the less time you need for a ride}
speed time
10 m/s 75 s
8 m/s x
![x=\dfrac{10\cdot75}{8}=93.75\,s](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B10%5Ccdot75%7D%7B8%7D%3D93.75%5C%2Cs)
2. price and kolos of apples - the higher the pice the less of kilos you can buy by given cash
price kilos of apples
$2 8
$4 x
![x=\dfrac{2\cdot8}{4}=4\,kg](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B2%5Ccdot8%7D%7B4%7D%3D4%5C%2Ckg)
